Abstract: A connector assembly comprises a base part that defines a through-hole for receiving a bolt and also defines an aperture for receiving a device having a first end that fits through the aperture in the base part and a second end that does not fit through the aperture in the base part. The first end of the device defines a bolt-hole for engaging with a bolt extending though the through-hole in the base part. The second end of the device comprises opposing outer surfaces that engage the base part and thereby prevent the device from passing completely through the aperture, and also align the bolt-hole in the device with the through-hole in the base part when the first end of the device is inserted into the aperture.
